We have to remove the loadPDF variants using InputStream and replace them with
RandomAccessRead.
If it comes to InputStreams users have to decide how to procide:
* copy the InputStream to memory by using RandomAccessReadBuffer
* copy the InputStream to a file and use RandomAccessReadBufferedFile or
RandomAccessReadMemoryMappedFile
This would make it more transparent what happens under the hood when using the
different kinds of loadPDF methods:
* a byte array as source is already in memory and the obvious choice is to use
RandomAccessReadBuffer as a wrapper
* a file as source targets a local file and the most obvious choice is to use
RandomAccessReadBufferedFile as a wrapper. We should document that as the other
alternative RandomAccessReadMemoryMappedFile is offered in this case
* RandomAccessRead as source is the most obvious one and the user decides how
to create it. Additionally is ist possible to implement some own caching
loading and/or mechanism
